gzip: Tapes

1 6 Using ‘gzip’ on tapes
1 ***********************
1 
1 When writing compressed data to a tape, it is generally necessary to pad
1 the output with zeroes up to a block boundary.  When the data is read
1 and the whole block is passed to ‘gunzip’ for decompression, ‘gunzip’
1 detects that there is extra trailing garbage after the compressed data
1 and emits a warning by default if the garbage contains nonzero bytes.
1 You can use the ‘--quiet’ option to suppress the warning.
